Improved brush

IIMPROVED BRUSH.

The Schedule referred to in these Letters Patent and making part of the sama To all 'whom it may concern: 1

Be it known that I, SAMUEL Bnrnmnenn, of -Glarence Centre, in the county of Erie, and State of New York, have invented a certain new and useful Improvement in Brushes; and I do herebyfdeclare that the following is a full and exact description: thereof,

reference being had to the accompanying drawings, making part oi' this specication, in which- Figurel is a vertical section 'of the brush.

Figure 2` is a perspective view of the expanding'- nut, with the defenders attached.

My invention is for the purpose of using and preserving the same handle and stock of apaint-brush,

so that whenone set of bristles is usedv up, another its lower end, which 4screws into a cone-shaped metallic socket B, forming a circular wedge or ycone,-which Vmakes part of the handle, and which screws into and `forces outward the sectional nut a. u a, surrounded by the bristles b, against the ordinary outervrim C. A

Tokeep the bristles from getting into the spaces between the staves, when forced apart by the socket B, I place' defenders, c e,"over eachspace, bending one edge, and inserting it into a corresponding groovein each section of the nut, as clearly shown in iig. 2, the otherpart overlapping the next section, thus covering the space between.

Glue-or cement'can be used to hold the bristles together, asis usual in all brushes.

The novelty in this invention consists, essentially, in the employmentrof the conical'screw B, entering directly the sectional'nut a, a', and expanding it to hold the bristles without the interposition or agency of any other device or cement whatever, thus using but two essential parts. By this means, it-wil1 be seen that it is only necessary to screw or unscrew the handle directly from tl1e'top,without projecting the cone down into the body of the brush below the cover. f

I am aware, that in other brushes sectional staves have been expanded,rby theturning down of the. handle, as in Wm. H. Forkers patent, of November 5th, 1867 but in that case he 'has to project the yscrew down into the body of the brush, and has to employ,

in addition to the staves and the screwa loose nut, making a third element, which not onlyrenders the device expensive'anddifiicnlt to keep in working-order, on--account of the complicated interior construction, but renders it difficult tov insert and remove the handle. By using the two parts, viz, the conical screw and the sectional nut, I remedy these difiiculties, for the handle vis simply screwed in and out at the top,

and does not run down deep in the brush.

I am also aware that a conical-pointed handle has been long in use,for simplyscrewing down into the bristles, and expanding them against the encirclingband, by the action of the entering cone itself, below the top of the brush. In such case, asy thel sectional stavesor nut is dispensed with, it is not the equivalent -of my invention. r

This simple screwing of the handle in at the top,

vthus expanding the nut to hold the bristles in place,

puts the whole device in the best possible form for' use, as thel brush can be tightened or loosened at pleasure. The handle can be removed at any time, for any purpose, and the bristles can be replacedwithout removingl and adjusting a complicated yand troun blesome interior arrangement. This is of great consequence, as, in ordinary use, the bristles wear out in a week or ten days.

To renew the bristles, vall that is necessary, is to unsorew the handle, remove the sectional nut, and the bristles will drop ont. Its mostimportant feature, I consider, is allowing the bristles to be renewed at will. My device is entirely for the purpose of saving `an I do not claim, either, an entering-cone or expand ing staves, in themselves alone,y as am aware that both have been before employed,l but none arranged 2. In combination with the sectionalnut a, the dcfenders 'c' e, arranged as described, and operatingin l v.the manner and for the purpose specified.

In witness whereof, I have hereunto signed my Yname in the presence of two subscribing witnesses. SAMUEL BRILLINGER.
